ABSTRACT:
A central differential has first and second output members for distributing power of an engine through a transmission to front and rear wheels respectively, and has a third output member for controlling distribution of the power. A first friction clutch is operatively connected to the second and third output members for restricting differential operation of the central differential and for controlling distribution of the power to the front and rear wheels. A second friction clutch is operatively connected to the second output member and either of the front or rear wheels. The first friction clutch is disposed at the innermost position and the second friction clutch is disposed around the first friction clutch so as to effectively transmit and distribute power to each wheel in compact and simple structure.
